TQ3GeometryObject triGrid, 
unsigned long rowIndex, 
unsigned long columnIndex, 
TQ3Point3D *position);
triGrid
A trigrid.
rowIndex
A row index into the vertices array of the specified trigrid.
columnIndex
A column index into the vertices array of the specified trigrid.
position
On exit, the position of the specified vertex.
